Data Recovery from Seagate 7200.11, 7200.3 & ES.2 hard disk drivesThe Seagate Barracuda 7200.11, 7200.3 & ES.2 series of hard drives can develop a unique problem that causes access to the data they contain to be lost. This problem is apparent on 7200.11 & ES.2 drives with the following capacities: 500Gb, 750Gb, 1Tb and 1.5Tb. Fortunately, Data Clinic are able to fully recover the data from these drives. Example Models:
Unique failure symptoms:
Cause: The fault stems from a firmware issue that set an invalid boundary value for the drive’s ‘circular event log’. Where this coincides with a particular test pattern being placed in the system tracks of the reserved area by some of Seagate’s post manufacture ‘tester’ applications, the event log pointer is incremented beyond its allowable boundary. This is detected as an ‘Assert Failure’ by the drive which ‘freezes’ as a self-protection response. Once this occurs the drive is remains inoperable however many times it is subsequently powered up. The unpredictable nature of the problem means that it is near impossible to say whether or when drives with the firmware in question will fail. Notes Remember that in addition to the above symptoms, these hard drives are still susceptible to failure in all the normal ways !! - click here for common hard disk failure symptoms.
